THEODORE E SCHWARTZ FIG. 5.

United States Patent Ofice 3,432,864 Patented Mar. 18, 1969 3,432,864 URINAL Theodore F. Schwartz, 1166!) St. Andrews Way, Scottsdale, Ariz. 85251 Filed Feb. 27, 1967, Ser. No. 619,535 U.S. Cl. 4-110 Claims Int. Cl. E03d 13/00; A471; 11/02 ABSTRACT OF THE DISCLOSURE A disposable urinal for female patients in supine position, the urinal having an opening adapted to fit the genitalia of the patient from the anterior wall of the vagina to a position above the urethral orifice; the urinal also having a urine receiving container extending at an angle downwardly below the engagement of said opening with said anterior wall of said vagina.

This invention relates to a urinal, and more particularly, to a disposable urinal which may be used in hospitals, or other areas, to alleviate the cost of maintaining conventional urinals.

In hospitals, conventional urinals must be stored, transported, sterilized, and thus are not only bulky, but generally costly to maintain. Additionally, due to the maintenance problem, it has been necessary to employ conventional urinals, which of necessity, cannot conform closely to the genitals of human females. The conventional urinals must have an opening of suflicient size to permit proper cleaning maintenance, which it has been diflicult with such urinals to properly place them with respect to female patients in a supine position, and to thereby maintain the patient in a comfort needed condition during urination.

Accordingly, it is an object of the present invention to provide a very simple and economical disposable urinal, which greatly alleviates the maintenance cost of urinals in hospitals, and further provides for additional comfort of patients, and particularly female patients, when urinating in a supine position.

Another object of the invention is to provide a disposable urinal, which may be made of very cheap material, which is so designed that the parts thereof may be nested into substantially compact relation to each other, thereby greatly alleviating the overall cost of storage, and maintenance of urinals in hospitals or other similar establishments.

Another object of the invention is to provide a disposable urinal of novel construction, which also employs a human female genital engaging rim, which extends generally from the anterior wall of the human vagina to a position slightly above the clitoris so as to comfortably fit the human female during urination, and to prevent undue spillage of urine during urination of the human female, when in supine position.

Another object of the invention is to provide a novel disposable urinal comprising a hollow receptacle body, which generally diverges from a receiving opening to an open bottom end, and wherein the receiving opening is relatively small, and the open bottom end is relatively large, and wherein means is provided for resiliently frictionally sealing the bottom open end by means of a bottom member, such that the body structures of the urinal may be nested, and whereupon immediately before use, the bottom members may be frictionally and sealingly attached to the bottom members to enclose the open bottom of the body member for holding urine.

Further objects and advantages of the invention may be apparent from the following specification, appended claims, and accompanying drawings, in which:

FIG. 1 is a top or plan view of a urinal, in accordance with the present invention;

FIG. 2 is a sectional view, taken from the line 2-2 of FIG. 1;

FIG. 3 is a view taken from the line 33 of FIG. 2, showing the receiving end of the urinal;

FIG. 4 is a fragmentary view similar to FIG. 1, showing the receiving end of a modified form of the invention; and

FIG. 5 is a fragmentary view similar to the right hand portion of FIG. 2, but showing the modified structure of FIG. 4 in section.

As shown in FIG. 1 of the drawings, the urinal of the invention is provided with a hollow receptacle body 10. This body 10 is generally diverging from a receiving end 12 thereof to a bottom end 14 thereof. The receiving end 12 is provided with an opening 16 having a rim 18 surrounding the opening 16, and this rim 18 is adapted to engage genitals of a human female, so as to reach generally from the anterior wall of the vagina to a position slightly above the clitoris. The lower portion 20 of the rim 18 being adapted to engage the anterior wall of the vagina, and the upper portion of the rim designated 22, being adapted to engage the area slightly above the clitoris, thus, the rim 18 is so designed to sealingly engage the genitals of a human female to permit urination into the interior of the hollow receptacle body 10. This body 10 at its open end 14 is provided with an endless rim 24 having an endless channel structure 26 provided with a groove or recess 28 therein, which frictionally and resiliently holds and grips an inwardly directed annular rim or flange structure 30 of the receptacle bottom 32. Thus, the open bottom 14 is sealingly enclosed by the bottom member 32, as hereinbefore described, so as to permit substantial nesting of a plurality of the hollow diverging receptacle bodies, and to permit the bottom members 32 to be engaged and sealed relative thereto immediately before use.

An annular shelf 41 of the channel structure 26 projects outwardly from the body 10 to provide ease of handling by human fingers for pressing the bottom 32 into frictional sealing connection with the body 10, as hereinbefore described.

The body 10 at a neck portion 34 thereof closely adjacent to the open end 16 is provided with a vent opening 36 adapted to permit air to escape from the interior of the urinal of the invention during urination thereinto. This vent opening 36 is necessary since the rim 18, as hereinbefore described, is adapted to make a very close fit and seal relative to the genitals of a human female.

It will be seen that the receptacle body 10 is provided with side walls 38, which diverge from the neck portion 34 toward the open end 14. As shown in FIG. 2, the diverging structure of the hollow receptacle body is offset downwardly relative to the genital engaging rim 18 so as to contain urine below the level of the female genitals, when a female is urinating into the hollow receptacle body 10.

In the modification, shown in FIGS. 4 and 5, the neck 34 is similar to that shown in FIGS. 1 and 2, and the rim 18 is also similar, while the vent opening, designated 40 in FIGS. 4 and 5, forms a notch in the rim 18, and thus is modified with respect to the vent opening 36, hereinbefore described, which is spaced from the rim 18.

From the foregoing, it will be appreciated that the body 10, and bottom member 32 may be made of various disposable materials, including plastic or combinations thereof with paper or other fibrous materials, and that due to the generally diverging character of the hollow receptacle body members, that several of these may be nested to save and conserve space, and that the bottom members 32 may be forced into place sealingly to enclose the open bottom end 14 of the respective receptacle body 10 immediately before use.

Said plastic materials may have a low rate of heat transfer so as to be comfortable to the user.

The material of which the urinal is made, may be disposed of in a conventional incinerator, and once the disposable urinals are used, they may be discarded, and burned or collapsed so that the storage problem thereof is reduced to a minimum. The new urinals being nested are quite compact, and do not require much space, and the cleaning and sterilization of urinals in hospitals may thus be completely eliminated and dispensed with.

It will be understood that the bottom member 32 is flat, and provides a base upon which the urinal may be rested to contain urine, and preliminary to the emptying and disposing of the urine therefrom, The downwardly ofifset disposition of the body of the urinal, as shown in FIG. 2, provides a natural geometry by which the urinal may be located for urinating operations, and further, this offset relation provides a normal orientation for the vent 36 or the vent 40 of the modified structure, shown in FIGS. 4 and 5.

It will be obvious to those skilled in the art that various modifications of the present invention may be resorted to in a manner limited only by a just interpretation of the following claims.

I claim:
